    摘要： The present invention has an object to provide a phase shifter, a wireless communication apparatus, and a phase control method in which power consumption is reduced. A phase shifter according to the present invention includes a 90° step phase shifter (17) and a 45° phase shifter (18) and adds phase information to two baseband signals to be output to an orthogonal modulator. The 90° step phase shifter (17) contributes to adding any one of phases 0°, 90°, 180°, and 270° to the baseband signals according to a first control signal. The 45° phase shifter (18) contributes to adding one of phases 0° and 45° to the baseband signals according to a second control signal. A phase shifter (8) performs replacement of component signals of one of the baseband signals with component signals of the other of the baseband signals and inversion of polarities of the component signals.

    摘要： An access point in a multi-antenna system broadcasts data using spatial spreading to randomize an 'effective' channel observed by each user terminal for each block of data symbols broadcast by the access point. At the access point, data is coded, interleaved, and modulated to obtain N D data symbol blocks to be broadcast in N M transmission spans, where N D ‰¥1 and N M >1. The N D data symbol blocks are partitioned into N M data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and broadcast via N T transmit antennas and in one transmission span to user terminals within a broadcast coverage area.

    摘要： Aspects for balancing power output on the plurality of antennas for the transmission of a transport block are disclosed. In accordance with the present disclosure, a transmitter may balance the power output on a plurality of transmit antennas in a multiple-input multiple-output (MIMO) system by having a precoded data block bypass a virtual antenna mapping of the overhead channels (e.g., control channels). Additionally or alternatively, the transmitter may balance the power output on the plurality of transmit antennas by applying an inverse mapping parameter during the precoding process to the transport block to generate a plurality of inverse mapped precoded data blocks. In some examples, the inverse mapping parameter may be an inverse of the mapping parameter. Thus, in accordance with the present disclosure, precoding a transport block may include selecting a precoding weight for each of the plurality of antennas from an unrestricted precoding weight set.
